Minyak atsiri mengandung berbagai senyawa bioaktif, termasuk antioksidan yang berpotensi dimanfaatkan sebagai bahan aktif tabir surya. Penelitian ini bertujuan menentukan nilai Sun Protection Factor (SPF) beberapa senyawa murni minyak atsiri, mengevaluasi karakteristik mutu krim tabir surya, serta menganalisis pengaruh jenis senyawa dan konsentrasi vaselin album terhadap nilai SPF, sifat fisik, dan sensori sediaan. Penelitian dilakukan dalam dua tahap. Tahap I merupakan skrining lima senyawa murni, yaitu limonene, β-pinene, linalool, γ-decalactone, dan citronellol untuk memperoleh nilai SPF tertinggi. Tahap II mengaplikasikan tiga senyawa terpilih (citronellol, β-pinene, dan linalool) dalam formulasi krim dengan variasi konsentrasi vaselin album 5%, 8%, dan 11%. Parameter yang dianalisis meliputi nilai SPF pada senyawa murni; serta pada krim meliputi SPF, pH, homogenitas, daya sebar, kelembaban, dan uji hedonik (tekstur dan aroma). Hasil skrining menunjukkan tiga senyawa dengan aktivitas tabir surya tertinggi, yaitu citronellol (SPF 38,3; proteksi tinggi), β-pinene (28,9; proteksi tinggi), dan linalool (22,5; proteksi sedang). Nilai pH krim berkisar 4,9–5,6 dan memenuhi standar SNI 16-4399-2016. Seluruh sediaan homogen tanpa butiran kasar. Daya sebar berada pada rentang 6,63–8,28 cm dan dipengaruhi oleh jenis senyawa, konsentrasi vaselin album, serta beban. Secara sensori, panelis lebih menyukai krim dengan penambahan citronellol dan β-pinene. Perlakuan terbaik adalah krim dengan citronellol dan vaselin album 11% (S1V3), dengan bobot jenis 0,95 g/mL dan viskositas 2074,5 cP. Uji cemaran mikroba menunjukkan hasil negatif terhadap jamur, Staphylococcus aureus, Pseudomonas aeruginosa, dan coliform, dengan angka lempeng total 7,83 × 10³ koloni/g.

Essential oils contain various bioactive compounds, including antioxidants that have the potential to be used as active ingredients in sunscreens. This study aims to determine the Sun Protection Factor (SPF) of several pure essential oil compounds, evaluate the quality characteristics of sunscreen creams, and analyze the effect of compound types and vaseline album concentrations on the SPF value, physical properties, and sensory properties of the preparations. The study was conducted in two stages. Stage I was screening five pure compounds, namely limonene, β-pinene, linalool, γ-decalactone, and citronellol to obtain the highest SPF value. Stage II applied three selected compounds (citronellol, β-pinene, and linalool) in a cream formulation with varying vaseline album concentrations of 5%, 8%, and 11%. The parameters analyzed included the SPF value of the pure compounds; and in the cream including SPF, pH, homogeneity, spreadability, moisture, and hedonic tests (texture and aroma). The screening results showed three compounds with the highest sunscreen activity, namely citronellol (SPF 38.3; high protection), β-pinene (28.9; high protection), and linalool (22.5; moderate protection). The pH value of the cream ranged from 4.9 to 5.6 and met the SNI 16-4399-2016 standard. All preparations were homogeneous without coarse grains. The spreadability ranged from 6.63 to 8.28 cm and was influenced by the type of compound, the concentration of vaseline album, and the load. Sensori- cally, panelists preferred the cream with the addition of citronellol and β-pinene. The best treatment was the cream with citronellol and 11% vaseline album (S1V3), with a specific gravity of 0.95 g/mL and a viscosity of 2074.5 cP. Microbial contamination test showed negative results for fungi, Staphylococcus aureus, Pseudomonas aeruginosa, and coliform, with a total plate count of 7.83 × 10³ colonies/g.
